A kind of air cleaning unit for plating tank
Technical field
The utility model relates to a kind of electroplating device, is specifically to support the use with plating tank, and can implements the device of purifying treatment to the air above the plating tank opening end, is particularly useful for using the manual work plating tank to carry out the occasion of electroplating activity.
Background technology
At present, in electroplating industry, plating tank is the major equipment in the electroplating activity process, and its effect is exactly to treat electroplating parts to implement electroplating activity.On electroplating assembly line, the kind of plating tank mainly is divided into two kinds of mechanical work plating tank and manual work plating tanks, the mechanical work plating tank is that Work transfer device, gas barrier etc. is used in conjunction with plating tank, and by main control mechanism, they are carried out step and control, make each device by predefined sequential analysis, thereby complete electroplating activity.It is long-pending larger that this mechanical work is electroplated plating tank, and input cost is higher, usually is applicable to the workpiece of large-scale or longer size is implemented electroplating activity, and is suitable for batch production.For the small-sized workpiece of short run, if use the mechanical work plating tank to implement electroplating activity, higher cost drops into and often can not in time be recompensed, even can't be recompensed, thus the loss of enterprise of causing.In this case, use the manual work plating tank to implement electroplating activity to the short run miniature workpiece, material benefit more economically just seems.Traditional manual work plating tank is that the e Foerderanlage in the mechanical work plating tank is removed, and changes conveying workpieces manually into, and this plating tank is owing to being subject to operating personnel's restriction highly, common small volume.Its primary structure is above the forward and backward both sides of small-sized plating tank opening part, the flat mouth draught hood to be set, and the suction opening upper end of flat mouth draught hood is generally 100mm to the distance of plating tank opening part.During operation, manually the workpiece of electroplated is put into plating tank by operator, after the electroplated operation is completed, more manually workpiece is taken out by operator.But, when the operation, be usually located at the front side of plating tank due to operator, when picking and placeing workpiece, it easily is subject to the interference of front side flat mouth draught hood; And because the height of flat mouth draught hood is only 100mm, when the workpiece that operator is completed plating takes out, after the height of workpiece is higher than 100mm, the volatile matter that is produced by the workpiece surface electroplate liquid is difficult to discharge by draught hood, the air purification effect of working district is relatively poor, easily the healthy of operator is worked the mischief.
The utility model content
Problem to be solved in the utility model is to provide a kind of air cleaning unit for plating tank, adopts this device to implement electroplating activity, and operator picks and places workpiece can not interfered, and is difficult for the healthy of operator worked the mischief.
For addressing the above problem, take following scheme:
Air cleaning unit for plating tank of the present utility model comprises plating tank, and plating tank upper end open place is provided with draught hood, and draught hood is connected with air draft pipe.Be characterized in that described draught hood is positioned at the top of plating tank rear side, the suction opening lower end of draught hood is not less than the upper surface of plating tank, and the suction opening upper end of draught hood is to the height 〉=500mm of plating tank upper surface.
The further improvement of the utility model scheme is that the suction opening end face of described draught hood is skewed layout, and its lower end flushes with plating tank rear side cell wall, and its upper end is positioned at above the plating tank peristome.The suction opening of draught hood tilts to the plating tank peristome, can increase the exhausting area of plating tank peristome, makes the exhausting effect more desirable.
Further improvement project of the present utility model is on described air draft pipe, volume damper to be arranged.Like this, can according to actual needs, regulate the flow velocity of air quantity in draught hood.
Take such scheme, have the following advantages:
Because the air cleaning unit for plating tank of the present utility model only arranges draught hood at the rear side of plating tank, therefore, operator can not interfered with draught hood when the operation of plating tank front side.And, height 〉=500mm due to the draught hood suction opening, be that the height of suction opening is usually greater than the height of electroplating parts, when the workpiece of plating being completed when operator takes out, the volatile matter that the workpiece surface electroplate liquid produces can obtain sufficient exhausting and discharge, the working district good air purification effect can reduce the electroplate liquid volatile matter to the healthy harm that causes of operator.
Description of drawings
Fig. 1 is the structural representation of the air cleaning unit for plating tank of the present utility model.
Embodiment
As shown in Figure 1, the air cleaning unit for plating tank of the present utility model comprises plating tank 1, and plating tank 1 upper end open place is provided with draught hood 5, and draught hood 5 is connected with air draft pipe 4, and volume damper 3 is arranged on air draft pipe 4.Described draught hood 5 is positioned at the top of plating tank 1 rear side, and its suction opening 2 end faces are skewed layout, and suction opening 2 lower ends flush with plating tank 1 rear side cell wall, and suction opening 2 upper ends are positioned at plating tank 1 opening part top.Suction opening 2 lower ends of draught hood are not less than the upper surface of plating tank 1, and suction opening 2 upper ends are to the height 〉=500mm of plating tank 1 upper surface.
